Apple Macintosh IIfx Specs

The Apple Macintosh IIfx features a 40 MHz 68030 processor, a 68882 FPU, 4 MB of RAM, a 1.44 MB floppy drive or a 1.44 MB floppy drive and a 80 MB or 160 MB hard drive, and the option of an Apple Macintosh II video card in an easy-to-expand desktop case.

The Macintosh IIfx is the fastest model in the Macintosh II series partly due to then-superfast RAM that was unique to the IIfx, a level 2 cache, and advanced hardware that allowed some applications to be optimized explicitly for speed.
